Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a bath agent composition which is excellent in a warming effect and a moisturizing effect and does not produce a herbal medicine odor.

[0002]

2. Description of the Related Art A large number of bath agents have been known so far, and these bath agents include inorganic salts, crude drugs, oils, enzymes,
Many substances such as fragrances and pigments are mixed and used. Among these, crude drugs, especially medicinal plants, are known to have a bath effect such as an excellent warming effect when added to a bath water. In addition, alkyl phthalides, alkoxy phthalides and alkylidene phthalides contained in plant extracts such as plants of the Umbelliferae are known as components having excellent warming effect (Japanese Patent Laid-Open Nos. 2-167216 and 4-99714). Issue).

[0003]

However, when these phthalides are compounded in a foaming bath agent containing carbon dioxide or an acid which is a carbon dioxide generating substance and a carbonate,
There is a problem in that there is an unpleasant sensation when taking a bath because it produces a unique herbal medicine odor.

Therefore, an object of the present invention is to provide an effervescent bath agent composition which contains the above-mentioned phthalides and does not produce a crude drug odor when dissolved in bath water.

[0005]

[Means for Solving the Problems] In view of such a situation,
As a result of intensive studies by the present inventor, in a foamable bath agent composition, by using a fatty acid ester in combination with the phthalides, the crude drug smell of the phthalides when dissolved in bath water is suppressed and excellent. The present invention has been completed by discovering that it has a warming effect.

That is, the present invention provides the following component (A),
(B) and (C)

[0007]

[Chemical 2]

(Wherein R ¹ represents an alkyl group or an alkoxyl group having 3 to 14 carbon atoms, and R ² represents an alkylidene group having 3 to 14 carbon atoms), an alkylphthalide, an alkoxyphthalide, and One or more selected from alkylidene phthalides (B) Fatty acid ester (excluding nonionic surfactant) (C) Carbon dioxide gas or carbon dioxide generating substance is contained, and pH at the time of use is weakly acidic The present invention provides a featured bath agent composition.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Component (A) used in the present invention
Is one or more of the alkyl phthalides and alkoxy phthalides represented by the formula (1) and the alkylidene phthalides represented by the formula (2). Examples of the alkyl group having 3 to 14 carbon atoms represented by R ¹ in the above formula (1) include a propyl group, a butyl group, a pentyl group, a hexyl group, an octyl group, an isopropyl group and an isoamyl group. Examples of the alkoxyl group having 3 to 14 carbon atoms include an isopropoxyl group, a propoxyl group, a butoxyl group, a pentoxyl group and the like. Examples of the alkylidene group having 3 to 14 carbon atoms represented by R ² in the above formula (2) include an isopropylidene group, a propylidene group, a butylidene group, a pentylidene group and the like.

As the component (A), alkyl phthalides are preferable from the viewpoints of stability and activity maintenance. Among them, alkyl phthalides having an alkyl group having 4 to 8 carbon atoms are particularly preferable in view of performance and production. .

Some of the alkyl phthalides, alkoxy phthalides and alkylidene phthalides can be extracted from the rhizomes or roots of the plants belonging to the family Asteraceae. For example, they are synthesized by a known method in which phthalic anhydride is reacted with dialkyl cadmium or the like. be able to.

[0012] Since the plant extract extracted from plants such as the plants belonging to the Umbelliferae family contains various components in addition to the above-mentioned alkyl phthalide, alkoxy phthalide or alkylidene phthalide, an effective amount of this component is used. When added to the bath water, it emits a strong crude drug odor in combination with the above-mentioned phthalide-based crude drug odor, but such an irritating odor is also suppressed by using the component (B) described later together.

The alkyl phthalide, alkoxy phthalide and alkylidene phthalide may be used alone or in combination of two or more, and the addition amount to the bath water is 0.03 to 55 ppm when the concentration in the bath water is 0.03 to 55 ppm. , Especially 0.3-1
It is preferable to set it to 5 ppm. When it is less than 0.03 ppm, sufficient blood circulation promoting effect, warming effect and heat retaining effect cannot be obtained, and when it exceeds 55 ppm, it is unpreferable in terms of odor.

The fatty acid ester of component (B) used in the present invention includes isopropyl myristate, isopropyl palmitate, cetyl octanoate, octyl dodecyl myristate, octyl palmitate, octyl stearate, butyl stearate, myristyl myristate. , Stearyl stearate, coconut fatty acid ester, methyl laurate, 2-ethylhexyl palmitate, beef tallow fatty acid methyl, methyl stearate, isotridecyl stearate, methyl caprate, methyl myristate, methyl oleate, isobutyl oleate, octyl oleate. , Lauryl oleate, oleyl oleate, 2-ethylhexyl oleate, decyl oleate, octyldodecyl oleate, octyldodecyl behenate, beheate Phosphate behenyl, dioleyl adipate, polyoxyethylene bisphenol A laurate, and the like. In the present invention, of these, isopropyl myristate, methyl stearate, oleyl oleate, and polyoxyethylene bisphenol A lauric acid ester are preferable. The fatty acid ester may be used alone or as a mixture of two or more, and the mixing ratio thereof is not particularly limited, but from the viewpoint of formulation, it is 0.1 to 50 times by weight that of alkyl phthalide, alkoxy phthalide and alkylidene phthalide. It is preferable that the amount be 0.5 to 10 times by weight.

When carbon dioxide gas is blended as the component (C), it is prepared by filling the bath agent composition in a sealed container and injecting carbon dioxide gas at 1 atm or more. Further, as the carbon dioxide generating substance, a combination of an acid and a carbonate is preferable, and as the acid, either an organic acid or an inorganic acid can be used, but a water-soluble and solid one is preferable,
Among these, organic acids such as succinic acid, fumaric acid, malic acid, adipic acid, tartaric acid, benzoic acid, citric acid, pyrrolidonecarboxylic acid and salicylic acid are particularly preferable. Examples of the inorganic acid include boric acid, metasilicic acid, and silicic acid anhydride. As the carbonate, sodium carbonate, sodium hydrogen carbonate, magnesium carbonate, potassium carbonate and the like are preferable. These acids and carbonates can be used alone or as a mixture of two or more selected from each.

The amount of the acid and the carbonate to be mixed is not particularly limited, but the pH of the bath water is set to 5 by appropriately selecting the ratio of the acid and the carbonate to be mixed.
When it is adjusted to 7 (0.01% by weight aqueous solution), it is possible to allow carbon dioxide gas in the bath water to exist in a dissolved state, and thus it is possible to obtain a bath agent composition excellent in blood circulation promoting effect and the like. it can.
